BMW N54 135/335i Remapping

July 2011 

We have recently remapped many BMW N54 135/335i’s with outstanding results with just Stage 1 software. This client struggled to make more than 280whp. We worked our magic and loaded the GIAC Stage 1 race file and the car went straight onto the dyno without any ECU adaptation. Proof is in the pudding: 321hp and 502Nm at-the-wheels.
